It’s a well-known fact that Halloween is our favorite holiday at Steve Spangler Science. It’s time for spooky, bubbling, oozing and glowing science. You are never too old to love a good spine tingling scare or gross out. Children also love a good startle or ick moment. Just make it fun as to not cause them childhood traumas for therapy later on in life. I love to try out my concoctions on visitors to our house and rate their heebie jeebies factor.
Maybe you love Halloween as much as I do and you are designing a haunted house in your basement, backyard or garage this season. Grab those kids and science materials and invite the friends and neighbors over for a frightfully good time. Here are my haunted house ideas for Halloween decorations, activities and props.
BLACK LIGHTS
Black lights are essential for haunted house displays. They make everyday white items like socks and t-shirts glow in the dark. They also charge Glow Powder or zinc sulfide and Atomic Glow – perfect for all of those glowing concoctions.
DRY ICE
The most important material for

We love to see a twist or a new idea for one of our experiments and activities. One of our favorite bloggers Janelle at Brimful Curiousities, shared this idea on her blog. We loved it so much, we want to share it with our readers…
Janelle took our Screaming Balloon activity one step further and made ghosts with the balloons. First, she added the hex nut to the balloon and blew it up, just as the experiment explains. Then, she took white kitchen garbage bags and placed the balloons inside. She taped up the bag at the bottom of the balloon to keep the balloon from falling out of the bottom. Finally, she and her kids used black permanent pens to draw faces on the ghosts.
The ghosts can also glow by turning off the lights and placing a flashlight behind them.
The ghosts were named and played with for an entire evening. I’m sure her house was filled with whirring sounds and laughter. A science lesson about centripetal force also sneaked in.
An added bonus for using the garbage bags is if and when the balloon pops, the hex nut is
